I'm going through a hub with USB-A connectors so the CC pins and the Superspeed side channel signals do not make it to the host. The cable I've been working with enumerates other USB-C peripheral so I don't think this is it either, but I will test a different cable to rule it out. Maybe it is a buil...

I also scoped the levels of GPIO3, GPIO45, GPIO46 during power on, and these are all LOW. GPIO0 is button controlled.

Yes, but the board does not enumerate over the USB port under a BOOT power on or a normal power on. The module prints this out the UART port with the BOOT button pressed: ESP-ROM:esp32s3-20210327 Build:Mar 27 2021 rst:0x1 (POWERON),boot:0x0 (DOWNLOAD(USB/UART0)) waiting for download Under a normal b...

I built up a prototype PCB and I can't seem to get the USB port to communicate. The USB hardware configuration seems easy enough GPIO19 (Pin 13 on ESP32-S3-WROOM-1-N8R2) connects to D- and GPIO20 (Pin 14) connects to D+. Here is a image of the layout: Screenshot 2023-12-13 at 4.24.44 PM.png The UART...

I figured out a solution. The MTS transducer was reconfigured to a PWM output: Start = __|----|____________________|----|___... PWM = ____|--------------...---------|_____|-------... Then used a GPIO interrupt on the falling edge of the PWM signal to retrigger the RMT TX signal, and used the rising ...

Can the RMT ISR be triggered after one data bit is complete? I am working with a MTS Transducer ( http://www.mtssensors.com/fileadmin/media/pdfs/Products/Industrial/G_Series_GP_GH_Analog_DPulse.pdf ) with a "Start/Stop" interface. This works by the host (a ESP32-WROOM-32 module) generates a start pu...
